Begonia erythrofolia, a new species of Begonia sect. Platycentrum (Begoniaceae) from Yunnan, China is described and illustrated. Morphologically, it is most similar to B. dielsiana and B. edulis, but differs in having broadly ovate leaves which are undivided or shallowly triangular lobed, crimson on the abaxial leaf surface, and more veins in the lamina. The new species also resembles B. subhowii in its similar leaf shape and in having erect stems when flowering, but differs in its larger leaf size, and smaller bracts and flowers.
